CR2 to MXF Converter

CR2 to MXF: What This Tutorial Covers

This is a niche conversion: you have a Canon CR2 raw photo and a workflow that ingests MXF — a still image that needs to become a single-frame broadcast asset, a slate, or a test card inside a newsroom or playout system. This page walks through how the tool builds a silent MXF clip from your photo, what gets downscaled along the way, and the (common) case where you should convert the CR2 to a JPG or MP4 instead.

How to Convert CR2 to MXF

1. Upload Your CR2 File: Drag and drop your .cr2 photo onto the page or click "+ Add Files". You can queue several stills; Merge images strings them into one clip, while Video per image writes a separate MXF per photo.
2. Set the Video Codec and Duration: Open Advanced Options. The output defaults to the MPEG-2 Video Codec and PCM audio track MXF expects, and Duration controls how many seconds your still holds on screen (default 5). Switch the codec to H.264 only if your target system specifically accepts AVC-in-MXF.
3. Choose Video Resolution (Optional): Leave Video resolution on Keep original to keep the full photo, or pick a Preset Resolution (e.g. 1920x1080) so the frame matches a broadcast raster instead of the camera's ~20-megapixel dimensions.
4. Convert and Download: Click "Convert" and save your .mxf file. No sign-up, no watermark.

Walk-through: Turning One Photo into a Broadcast Frame

A CR2 is a raw still — it has no motion and no audio — so the tool does two jobs at once: it renders the raw sensor data into a viewable picture, then holds that picture as video for the duration you set. Two settings carry most of the outcome:

• If your playout system lists a specific raster (1080p, 720p): set Video resolution to the matching Preset Resolution. A modern Canon CR2 is roughly 5472x3648 (about 20 megapixels), far larger than a 1920x1080 frame, so leaving it at full size produces an oversized image that ingest tools may reject or rescale unpredictably. Downscaling to the target raster up front is the safer path.
• If the asset is a slate or holding card: a few seconds is usually enough — keep Duration short (3-5s) so the file stays small. Use a longer duration only when the still needs to fill a fixed gap in a playlist.
• The MXF carries a silent PCM audio track by definition, but a photo contributes no sound, so the output is silent. That is expected for a still; if your system needs tone or bars under the slate, add them in your playout tool, not here.

Common Errors and How to Fix Them

• "The image looks flat, off-color, or differently exposed than my camera preview" — A CR2 stores raw sensor data that must be demosaiced and white-balanced before it is viewable; the rendered frame reflects a neutral interpretation, not Canon's in-camera JPEG look. For a color-managed result, render the raw in your editor first, export a TIFF or PNG, then bring that into the converter.
• "The MXF frame is the wrong size for my system" — The still kept its full ~20-megapixel dimensions. Re-run with Video resolution set to the Preset Resolution your ingest spec lists (commonly 1920x1080).
• "My playout tool rejected the file" — Many broadcast systems validate a specific operational pattern, codec, or frame rate. Confirm whether it wants OP1a MPEG-2 (the default here) or something stricter like a fixed-rate AVC-Intra; this tool produces a general-purpose OP1a-style MPEG-2 wrapper, not every facility-specific profile.
• "The output has no sound" — That is correct. A single photo has no audio, so the clip is silent.

When This Doesn't Work

This conversion only makes sense when something genuinely ingests MXF — a newsroom MAM, a playout server, or a QC tool that rejects anything that is not .mxf. In a tapeless broadcast chain, a still slate or holding card is exactly the kind of asset that historically moved on tape and now travels as MXF. If you are not feeding such a system, you almost certainly want a normal image or video instead: convert the CR2 to a JPG for a shareable photo, or to an MP4 if you want a clip that plays everywhere. For very strict facility profiles (AVC-Intra at a locked bitrate, specific timecode rules), a dedicated broadcast encoder will give you controls this general converter does not.

Frequently Asked Questions

Why would anyone convert a CR2 photo to MXF?

The honest answer is: rarely, and only for broadcast plumbing. MXF (Material eXchange Format, SMPTE ST 377-1, first published 22 September 2004) is the wrapper newsroom, playout, and archive systems ingest. A still photo sometimes has to enter that chain as a single-frame asset — a slate, a test card, or a holding image. In a tapeless workflow that role, which once lived on videotape, is now filled by MXF. If you are not delivering into an MXF-based system, you do not need this conversion; convert to JPG or MP4 instead.

Will the MXF look exactly like my Canon photo?

Not necessarily. A CR2 is Canon Raw v2 — raw sensor data built on a TIFF structure, typically carrying 12 or 14 bits per channel. Raw data is not a finished picture: it must be demosaiced, white-balanced, and tone-mapped to become viewable. The converter renders it with a neutral interpretation, which can differ from Canon's in-camera JPEG. For a precise look, develop the raw in your editor, export a TIFF or PNG, and convert that.

What codec and audio does the MXF output use?

The video essence defaults to MPEG-2, the codec most broadcast and edit systems reliably ingest from an MXF wrapper, written as an OP1a-style self-contained file. H.264 is also offered if your pipeline accepts AVC-in-MXF. MXF defines a PCM (16-bit) audio track, but because a photo carries no sound, the output is silent — the audio side is effectively moot for a still.

Does my 20-megapixel CR2 stay full resolution in the MXF?

Only if you leave Video resolution on Keep original. A modern Canon CR2 is around 5472x3648, which is far larger than broadcast frames like 1920x1080. Most ingest workflows expect a standard raster, so set Video resolution to a Preset Resolution that matches your delivery spec; the tool downscales the still to that frame.

How long does the still stay on screen, and can I change it?

Yes — the Duration control sets how many seconds the photo holds, defaulting to 5. For a slate or holding card, a short duration (3-5 seconds) keeps the file small; choose a longer value only if the asset must fill a fixed gap. In our testing, a single CR2 rendered to a 1920x1080 MPEG-2 MXF at a 5-second duration produced a compact clip dominated by the still frame rather than motion data.

How are my files handled, and how long are they kept?

Your CR2 is uploaded over an encrypted (TLS) connection, processed on our servers, and the files are deleted automatically a few hours after conversion. There is no sign-up, no watermark on the output, and your files are never shared or made public. The main thing to watch with raw stills is upload size, since a CR2 is a large file — but the rendered MXF frame itself is modest at a short duration.
